• Nuclease activity associated with cells and protoplasts was analyzed by agarose gel electrophoresis. Datura innoxia protoplasts were found to possess a high exonuclease activity. On the other hand, Datura innoxia cells had an endonuclease activity, but no apparent exonuclease. The exonucleases from the protoplasts were active at pH 5 and 6, but not at pH 9. Endonuclease activity from the cells was also inhibited at pH 9. Cultured cells of Daucus carota, Glycine max, Pisum sativum and Vicia hajastana had endonuclease activity, but did not exhibit exonuclease activity. Nicotiana suaveolens cells had both types of nuclease activity. On the other hand, cells from cereals such as Triticum monococcum, Oryza sativa, and Zea mays had active exonuclease activity.
